Installation

Currently, the only way to install OpenWrt is to build Backfire and transfer the resulting image to the router via serial port. Please consult here (Midge). Here is a good HOWTO on installing a serial port.

Main PCB:
The main PCB of BR-6104K with modifications. USB components were filled in and quick hack of +5V USB power supply added which virtually made it to work like BR-6104KP. Also the second serial port was connected to JP2 connector (no 3.3V to RS232 level converter shown).

Serial

On the BR6104K/KP board there is a 8pin connector called JP2 that can be used as serial port. You can connect a serial level shifter (such as the MAX232 family) to these pins.

Its pins are:

1.RX 2.+3.3V
3.nc 4.nc
5.nc 6.nc
7.TX 8.GND

Use the 3.3V as supply for the MAX chip, don't use the 5V from the USB. (You want to convert to the processors' levels, not the USBs')
